Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.

Abstract: Embodiments of the present disclosure relate to methods, a terminal device, a network device, and computer program products for SCell management in wireless communication. A terminal device receives from a network device configuration information for configuring a triggering mode. The triggering mode is for triggering activation of a secondary cell of the terminal device and a transmission of a temporary reference signal in the secondary cell. Based on the configured triggering mode, the terminal device receives first triggering information on the activation of the secondary cell and second triggering information on the transmission of the temporary reference signal for performing the activation of the secondary cell. In this way, it is possible to reduce the latency of activation/de-activation procedure for SCG and secondary cells.

Abstract: Some aspects include an apparatus, method, and computer program product for identifying a panel on user equipment (UE) for sounding reference signal (SRS) and/or physical uplink shared channel (PUSCH) communications. This panel selection may be applicable to codebook as well as non-codebook based PUSCH transmission schemes. In some aspects, a base station may provide the UE with an indication of one or more SRS resources and/or sets of SRS resources. The UE may then identify a panel corresponding to the indicated SRS resources and use this panel for PUSCH communications. In some aspects, the UE may apply prioritization scheduling when the UE uses different panels for SRS and PUSCH communications. This prioritization scheduling may address switching delays, which may occur when the UE switches between panels.

Abstract: A user equipment (UE) is configured to transmit physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) transmissions. The UE receives a downlink control information (DCI) transmission including a transmission power control (TPC) configuration, wherein the TPC configuration includes at least one TPC command, determines a subset of (i) multiple closed loop indexes or (ii) multiple beams for which the TPC command is configured, wherein the multiple closed loop indexes and multiple beams correspond to multiple transmission and reception points (TRPs) and applies the TPC command to one or more physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) transmissions corresponding to the subset of multiple closed loop indexes or beams.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) to multiplex a first HARQ of a first priority and a second HARQ of a second priority to form an initial UCI payload. The UE can select a PUCCH resource accordingly to a PUCCH configuration, and generate a second UCI payload by removing or replacing at least a portion of the initial UCI payload when a size of the initial UCI payload is larger than a size of the PUCCH resource. The UE can encode at least a part of the second UCI payload including the first HARQ to generate an error correction code word. Afterwards, the UE can add the error correction code word to the second UCI payload to generate a transmission UCI payload, and transmit the transmission UCI payload to the base station.

Abstract: A base station can support dynamic spectrum sharing (DSS) between new radio (NR) services and Long Term Evolution (LTE) services. The base station can determine whether a NR physical downlink control channel (PDCCH) control resource set (CORESET) and a LTE PDCCH frequency range are partially overlapped in a frequency domain including a first frequency region and a second frequency region. The partial overlap occurs when the LTE PDCCH frequency range overlaps with the NR PDCCH CORESET in the first frequency region without overlapping with the NR PDCCH CORESET in the second frequency region. In response to a determination that the partial overlap occurs, the base station can map a NR PDCCH or a NR PDCCH demodulation reference signal (DMRS) to resource elements in the second frequency region, and map a LTE cell-specific reference signal (CRS) to a symbol carrying the LTE CRS in the first frequency region.

Abstract: A method that determines a resource at a first user equipment (UE) for a sidelink communication from the second UE to a first UE is described. In an exemplary embodiment, the method receives a request from the second UE to send data to the first UE. In addition, the method determines a preconfigured resource selection window that is used by the second UE. Furthermore, the method determines a first sensing result at the first UE. The determined first sensing result includes information to be reported to the second UE for a resource selection. The determined first sensing results has a plurality of first sensing types. Further, the method transmits the first sensing result from the first UE to the second UE.
